This invention relates to a device by means of whlch a stream of gases carrylng solids in suspension can be dlvlded into two or more branches in such a way that a uniform distribution of the gases and solids 1s ob- The inventained in the different branches. tion is especially applicable for the purpose of dividing a stream of air carrying pulverized coal in suspension to be distributed to a plurality of burners for furnaces, but the invention is not restricted to this particular use.

Heretofore when attempts have been made 7 jection is largely or entirely overcome by the present invention and the several branches are provided with mixtures of gases and solids of like proportions.

The invention will be understood from the description in connection with the accompanying drawlng in which Flg. 1 1s a side View partly in section showing an illustrative embodiment of the invention; Fig.2 is a plan view partly broken away; and Fig. 3 is a plan view showing a' modification.

' In the drawing reference character 1 indicates a vertically disposed pipe or conduit through which a stream of gases carrying solids in suspension is passed. An L or somewhat L-shaped connection is connected to the upper end of the pipe 1. The portion 2 of the L or L-shaped member connected to the pipe 1 is of tubular shape and merges into a hollow portion 3 extending at an angle, preferably at a right angle, to the portion 2 that is connected to the pipe 1. The portion 3 has upper and lower walls 3 and 3 that expand outwardly somewhat fan-shaped, as

more clearly seen in Fig. 2. These walls converge toward their wide ends so that the cross sectional area of the portion 3 is approximately thesame from one end to the other. An angularly disposedwall 4, havingaflat surface at'an angle of say 45 to the axis. of the portion 2, is located in the I connection between the portions 2 and 3 in such ayposition as to be struck by the inconnng stream from the pipe 1. They upper ,end of the wall 1 is connected tothe end of I the upper wall 3 of the portion 3. YA corresponding wall 4. may be provided parallel to the wall 4 on the opposite-side therefrom .and is connected to the lowerwall 3 of theportion 3.

:The end, of the portion 3 opposite the slop ing wall 4 is divided into branches 5 that iincrease vertically'an'd decrease horizontally in size toward the exit ends. Pipes 6 are con nected to the'branches 5. Eachpipe 6 may,

for example, lead to a burner 7 for a furnace ;when the stream is air carrying pulverized fuel.

are located along the frontwall of a furnace The tubes 8 represent water tubes that which the burner? feeds. -.The.housing or compartment 9 indicates an. inlet for secondary air around the burner 7 for the fur nace. 1 T

In the modification shown iniFig. 3 the portion 3 is indicated as having two branches .5 leading to the pipes6 that may lead to burners. llilowever, the operation is not changed materially by varying the number of branches leading away from the por- In operation the stream of gases carrying solids is forced from the pipe 1 through the portion 2 and strikes against the fiat surface of the inclined or sloping wall 4, causing the same to splatter and thoroughly mix or commingle the gases and solids uniformly as they pass into the portion 3, so that each branch 5 will receive a mixture with the same proportion of gas to solids as the other branches.
